bt_icon not changing on state changed.

I am trying to change Icon of selected tab based on selection but not able to change it.

I am using Selector to switch the icons.
Icons do not support vector images (SVGs) below API level 23.

Use in activitymain.xml
```

```

Selector: home_tab_selector.xml
```

```

Moreover, **elevation** is not working as it should. Also not getting the **Shadow effect**.

Is there any other way to do so? Please let me know.

Thanks.
